For MegaRAID servers, you can execute the following commands to get the RAID status:
cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 02 Id: 00 Lun: 00
Vendor: LSI Model: MR9271-4i Rev: 3.29
Type: Direct-Access ANSI SCSI revision: 05
To get the drive information on the server
sudo storcli /c0 /eall /sall show
Controller = 0
Status = Success
Description = Show Drive Information Succeeded.
